Makes the user aware that SDSS Skyserver has failed as opposed to giving cryptic KeyErrors.

Example output:

In [21]: survey.get_catalog()
WARNING: Field info are not available for this data release [astroquery.sdss.field_names]
WARNING: Field info are not available for this data release [astroquery.sdss.field_names]

File ~/Python/FRB/frb/surveys/sdss.py:94, in SDSS_Survey.get_catalog(self, photoobj_fields, timeout, print_query)
